New York City is on Eastern Time. In winter that is Eastern Standard Time (EST, UTC−5); from the second Sunday in March to the first Sunday in November the city uses Eastern Daylight Time (EDT, UTC−4).

Business hours and markets
Most offices work roughly 09:00–17:00 or 18:00, Monday to Friday. The New York Stock Exchange and Nasdaq hold their regular trading session from 09:30 to 16:00 local time, which is why so much of the world watches Eastern Time.
Because New York is on the same daylight-saving schedule as the rest of the US, it stays 3 hours ahead of Los Angeles and 1 hour ahead of Chicago almost all year.
How daylight saving time works here
Clocks go forward at 02:00 local time on the second Sunday of March (02:00 becomes 03:00) and back at 02:00 on the first Sunday of November (02:00 becomes 01:00). That means 02:30 on the spring date never happens, and 01:30 on the autumn date happens twice.
Europe changes its clocks on different dates (the last Sundays of March and October), so for a few weeks each year New York is only 4 hours behind London instead of the usual 5.
Planning calls with New York
Morning in New York overlaps with the afternoon in Europe, making 09:00–12:00 Eastern the classic window for transatlantic meetings. Calls with India or the Gulf usually need to happen early in the New York morning.
